Back in January, Acer said that it would update its Iconia Tab A200 to Android Ice Cream Sandwich starting mid-February. And it looks like the company is keeping its promise, si several users are reporting over at the Acer Tablet Forum that the update (which brings Android 4.0.3) is available as of yesterday.

Of course, the update is being rolled-out gradually, so you A200 might not have received it yet. But you can always check manually for it (go to Settings / About tablet / System update / Check now).
